# Identity

`Class`

Main class for managing identity information in the Salesforce Marketing Cloud SDK.

The `Identity` class provides a singleton interface for managing user identity data, including profile information, custom attributes, and party identification details. All operations are performed thread-safely using an internal worker queue.

## Declaration

```swift
@objc(SFIdentity)
public final class Identity : NSObject

@objc
public func toJson() -> String

public func edit(identity updater: @escaping (IdentityModifier) -> IdentityModifier)

public func get() -> IdentityInfo?
```

## Cases

### `toJson()`

Converts the current identity information to a JSON string representation.

```swift
@objc
public func toJson() -> String
```

---

### `edit(identity:)`

Updates the identity information using a modifier closure. This method provides thread-safe access to modify identity data. The updater closure receives an `IdentityModifier` object that allows you to modify profile ID, attributes, and party identification information. All modifications are persisted to the database and trigger identity change events. Thread Safety: This method is thread-safe and uses an internal worker queue to ensure that identity modifications don’t interfere with other operations. Persistence: All changes made through this method are automatically persisted to the database and will trigger identity change events that other SDK modules can observe.

```swift
public func edit(identity updater: @escaping (IdentityModifier) -> IdentityModifier)
```

---

### `get()`

Retrieves the current identity information. This method returns the current identity data including profile ID, attributes, and party identification information. The data is retrieved from the in-memory cache for optimal performance. Thread Safety: This method is thread-safe and uses an internal worker queue to ensure consistent data access. Performance: This method retrieves data from the in-memory cache, making it very fast. If no identity has been set, it returns `nil` .

```swift
public func get() -> IdentityInfo?
```

**Returns:** An `IdentityInfo` object containing the current identity data, or `nil` if no identity record is found or if the identity manager is not properly initialized.
